Dzidza mienzaniso yematambudziko ekupindirana nekupararira kwechiedza - kutsemuka kamwe chete , wobva washanda pamatambudziko ekupindirana nekupararira kwechiedza.
1. Chiedza chine urefu hwemafungu e700 nm chinopfuura nemumupata une upamhi hwe0,2 mm. Patani ye diffraction iri pachiratidziro iri chinhambwe che50 cm kubva pamupata. Sarudza chinhambwe chiri pakati pemutsetse wechipiri werima nemutsetse mukuru wechiedza.
Kukurukurirana
Akabvunzwa: y?
Mhinduro:
Upamhi hwemugero hudiki zvikuru kana tichienzanisa nedaro riri pakati pemugero nechidzitiro (mumufananidzo upamhi hwemugero hwakakura) saka kona idiki kwazvo. Kona idiki zvekuti kukosha kwe sin theta kuri pedyo nekukosha kwe tangent theta.
Kureba pakati pemutsetse mukuru wakajeka nemutsetse wechipiri wakasviba i3,5 millimita.
2. Mupata mumwe chete une upamhi hwe 0,1 mm unovhenekerwa nechiedza che monochromatic uye pachidzitiro chiri mamita mana kubva pamupata, mitsetse yakasiyana-siyana, yakajeka neyakasviba, inogona kuonekwa nekuda kwekupararira. Kana daro riri pakati pemutsetse wechipiri werima nemutsetse mukuru wakajeka riri 16 mm, sarudza kureba kwechiedza!

Zvinozivikanwa kuti:
d = 0,1 mm = 0,0001 m = 1 x 10-4 m
l = 4 m
n = 2
y = 16 mm = 16 x 10-3 m
Akabvunzwa: chii chinonzi urefu hwechiedza?
Mhinduro:
Hurefu hwemafungu echiedza = 200 nanometers
3. Tarisa mufananidzo uri pazasi!
Mukana mumwe chete S ine upamhi hwe 0,2 mm inovhenekerwa nechiedza chakafanana chine λ = 500 nm (1 nm = 10-9 m). Patani yekubuda kwechiedza inotorwa pachidzitiro chiri 60 cm kubva pamupata. Daro riri pakati pemutsetse wechipiri werima nemutsetse wepakati wakajeka i…
A. 3,0 mm
B. 3,6 mm
C. 4,8 mm
D. 5,8 mm
E. 6,0 mm
Kukurukurirana
Zvinozivikanwa :
λ = 500 nm = 500 x 10-9 m = 5 x 10-7 m
d = 0,2 mm = 0,2 x 10-3 m = 2 x 10-4 m
l = 60 cm = 0,6 m
n = 2
Akabvunzwa : ye?
Jawab :
Upamhi hwemugero hudiki zvikuru kana tichienzanisa nedaro riri pakati pemugero nechidzitiro saka kona idiki kwazvo (upamhi hwemugero uri pamufananidzo uri pamusoro hwakakura). Kona idiki kwazvo saka kukosha kwesin tit kuswedera pedyo tit.
chivi θ ≈ tan θ = y / l = y / 0,6
Fomura yekuparadzanisa slit diffraction imwe chete (shoma):
d sin θ = n λ
(2x10-4)(y/0,6) = (2)(5 x 10-7)
(2x10-4) y = (0,6)(10 x 10-7)
(2x10-4) y = 6 x 10-7
y = (6 x 10-7) / (2 x 10-4)
y = 3 x 10-3
y = 0,003 mamita
y = mamirimita matatu

4. Mwaranzi wechiedza che monochromatic chine urefu hwemafungu e5000 Å (1 Å = 10 −10 m) chinopfuura nemumupata mumwe chete chinoburitsa patani ye diffraction yakajeka yekutanga sezvakaratidzwa mumufananidzo. Upamhi hwemupata nde…
A. 0,001 mm
B. 0,004 mm
C. 0,012 mm
D. 0,017 mm
E. 0,019 mm
Kukurukurirana
Zvinozivikanwa :

Akabvunzwa : upamhi hwemukana (d) ?
Jawab :
d sin θ = n λ
d (0,5) = (1)(5 x 10-7)
d = (5 x 10-7) / (0,5)
d = 10 x 10-7 m

Kupindira uye kupararira kwechiedza - mukaha mumwe chete
1. Mupata une upamhi hwe 0,5 mm unovhenekerwa nechiedza chine urefu hwewavelength = 650 nm. Patani ye diffraction iri pachiratidziro iri chinhambwe che 50 cm kubva pamupata. Sarudza chinhambwe chiri pakati pemutsetse wechipiri werima nemutsetse mukuru wechiedza.
2. Mupata mumwe chete une upamhi hwe 0,4 mm unovhenekerwa nechiedza che monochromatic uye pachikirini chiri mamita maviri kubva pa diffraction grating, patani ye diffraction yakajeka uye yakasviba inogona kuonekwa. Kana daro riri pakati pemutsetse wechitatu werima nemutsetse mukuru wakajeka riri 20 mm, sarudza kureba kwechiedza!
